When any organ in our bodies isn’t working correctly, you are more likely to feel fatigue because your body is working harder to push more blood to the organ in order to protect itself. If you suddenly feel weak, tired, and have trouble concentrating, you’re probably suffering from fatigue. Fatigue from a fatty liver affects more than just your alertness but your neurology too. When you suffer from fatigue for a long period of time you can become depressed or anxious because the body struggles to create serotonin. This can cause major changes in your mood. While there are many causes for fatigue, be on the look out for other symptoms to determine what exactly it’s from.
